Are you still in doubt about bitcoin? No matter what happens to bitcoin, our future depends on us. That is why today we have to be wise in investing. Bitcoin is volatile and that is a fact so we cannot predict the future. I believe in bitcoin value and that is enough for me.
Maybe he is not doubting but he is just asking how bitcoin can help everyone in terms of finances, just like other beginners, they ate always thinking that bitcoin is only for making people rich but they don't know how it could be, they also don't know some other purpose of bitcoin so they only focused on making their lives rich using bitcoin, cryptocurrency might be popular all over the world because there are already a lot of big names are interested with bitcoin.
